Evolutionary Limitation and Opportunities for Developing tRNA Synthetase Inhibitors with 5-Binding-Mode...

Area of Science:

• Biochemistry
• Molecular Biology
• Enzymology

Background:

• Aminoacyl-tRNA synthetases (aaRSs) are essential enzymes responsible for charging tRNAs with amino acids, a critical step in protein biosynthesis.
• Beyond their canonical role in translation, aaRSs in higher organisms have acquired diverse non-translational functions.
• The unique structural and functional characteristics of aaRSs across species present opportunities for therapeutic targeting.

Purpose of the Study:

• To summarize recent advancements in the discovery and development of aminoacyl-tRNA synthetase inhibitors.
• To review the latest structural studies of aaRS inhibitors.
• To classify identified aaRS inhibitors based on their distinct binding modes.

Main Methods:

• Literature review of recent studies on aaRS inhibitors.
• Analysis of structural data for aaRS-inhibitor complexes.
• Classification of inhibitors based on binding interactions and mechanisms.

Main Results:

• Numerous aaRS inhibitors have been identified and developed.
• Structural studies reveal diverse binding modes of these inhibitors.
• Inhibitors were categorized into five distinct classes based on their interactions with aaRS.

Conclusions:

• Aminoacyl-tRNA synthetases are promising therapeutic targets due to their essential roles in translation and non-translational functions.
• The structural diversity of aaRS inhibitors allows for targeted drug development against various diseases, including microbial infections and human disorders.
• Further research into aaRS inhibitor mechanisms and structures can lead to novel therapeutic strategies.
